Collection:

Collection ID:CO000931
Collection Summary:Bacterial cultures were grown overnight in M9 minimal medium plus 0.2% glucose and used to inoculate 2 mL of fresh medium to an optical density of 0.05 at 600 nm. Cultures were grown at 37°C with shaking for 5-6 h until optical density reached 1.7 ± 0.1 at 600 nm, then an equivalent of 1 mL culture at an optical density of 2.0 was collected in 1.5-mL Eppendorf tubes, centrifuged at 16,000 × g for 15 s; the pellet was frozen in liquid nitrogen. The harvesting procedure was completed in <30 s. Samples were stored at -80°C.
Sample Type:Cell

Treatment:

Treatment ID:TR000951
Treatment Summary:A= E. coli 12MG1655 (WT) B = E. coli yjeF gene knock-out C = E. coli point mutant K192A

Sample Preparation:

Sampleprep ID:SP000944
Sampleprep Summary:1. Add 0.5mL of extraction solvent to tube, gently pipet to remove all cells, transfer cells to 2mL eppendorf tube. Repeat for a total of 1mL extraction solvent + cells in 2mL eppendorf tube. 2. Add 2 small stainless steel grinding beads to eppendorf tube 3. Use the GenoGrinder to grind for 30 seconds at 1,250 rpm. 4. Centrifuge at 14,000xg for 5 minutes. 5. Transfer supernatant to a fresh 2mL eppendorf tube. 6. Add 1mL of extraction solvent to tube containing cell pellet + beads, and repeat steps 3 and 4. 7. Collect supernatant, and combine with supernatant collected in step 5. Total volume of extracted sample will be approximately 2mL. 8. Dry down 50uL of extracted sample in 1.5mL eppendorf tube for GC-TOF analysis. 9. Store backups in -20 or -80C.
